‘ONE FOR THE ROAD’ - NEW WHISKY BIOFUEL
23 August 2010
By-products from the whisky distilling process are being used to develop a bio-fuel, which could be available in a few years’ time on garage forecourts.
Researchers at Edinburgh Napier University have produced the fuel by using the two main by-products "pot-ale", the liquid from the copper stills, and "draff" the spent grains.
The new method produced by the researchers produces butanol, which gives 30% more power output than the traditional biofuel ethanol.
Project director Professor Martin Tangney, said using the waste products was more environmentally sustainable than growing crops specifically for biofuels.
